WELL-POINT.

SPECIFICATION forming part of Letters Patent No. 572,860, dated December8, 1896. Application filed July 15, 1896. Serial No. 599,256. (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, HENRY K. BREARLEY, of West Duluth, in the county ofSt. Louis and State of Minnesota, have invented a new and ImprovedlVelLPoint, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a Well-point constructed in asimple, durable, and economic manner, and which will pass through ore,clay, and rock much easier than the point ordinarily used.

A further object of the invention is to provide openings in the pointarranged to re ceive water and particles of earth and rock, which latterwill follow the pipe on the outside to the surface, so as to indicatethe nature of the strata through which the point is passing, and also toindicate when water has been reached.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improved well-point, the top beingin section and rep resented as coupled to a tube, the tube being also insection. Fig. 2 is a vertical section through a portion of thewell-point, and Fig. 3 is a horizontal section through the same.

The entire point is ordinarily made of caststeel, and the body A is oftapering shape, being largest at the top, and the lower end 10 of thebody is decidedly conical. Two flanges 11 are made integral with thebody or attached thereto in any approved manner, and these flanges arecarried spirally in opposite directions around the body from top tobottom. The flanges are of the same width throughout their entirelength, except at the top, where they gradually merge into the body ofthe point, and at the bottom, where the said flanges are given a taperin a downwardly direction, meeting the apex of the conical lowerextremity 10 of the body, and these tapering portions of the flanges arediametrically opposite and are sharpened to form cutting edges 12.Preferably in cross-section the flanges are triangular or essentiallyV-shaped, as shown in Fig. 3, being narrowest at their outer edges.

The body A is tubular, and it is provided with spirally-arrangedopenings 13, located between the flanges, and these openings areprovided with screens 14:. As the point is screwed into the earth waterthat may have been met will enter the openings 13 to their fullcapacity, and will thus indicate to the operator, when the pump isattached, whether or not water has been encountered.

The body of the point is provided with an interior or an exterior thread15 at its upper end, whereby it may be secured upon the end of a tubularsection 16, any desired number of the said tubes being employed, and thepoint is held to the tube 16 ordinarily by means of a pin 17, driventhrough the point and through the tube, as illustrated in Fig. 1, sothat the point may be withdrawn in the event water is not found.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A well-point comprising a tapering tubular body,flanges located exteriorly of the body and carried spirally around thesame in opposite directions, the flanges being of even width throughouttheir length except at the bottom and at the top, the lower ends of theflanges being tapered to meet the apex of the lower end of the bodywhich is closed and of conical form, the tapering portions of theflanges forming cutting edges which are diametrically opposite, the saidbody being provided with openings therein arranged at intervals inspiral order from top to bottom, the said flanges being substantiallyV-shaped in cross-section, and the body provided at the top with aninterior thread and a lockin g-pin, as and for the purpose set forth.

HENRY K. BREARLEY.
